For an entire winter, the young weather observer Anselm Straub must serve at the Zugspitze: conducting measurements, creating forecasts, and relaying all data by phone to Munich. It is the year 1906, and Straub lives in complete seclusion. Until he finds a completely exhausted woman in front of his meteorological station. She is the widow of a wealthy merchant, Lidia von Berneis. A 42-year-old adventurous woman who has become obsessed with the idea of climbing the highest mountain in the country all alone. But now there is no turning back. All paths are deeply snow-covered, threatened by avalanches, and impassable. She must stay with Straub for the entire winter. Thus, an extraordinary love story unfolds "on the high mountain." A story that is both sensitive and full of drama at the same time. And with an ending that no one would have expected. Stefan König, the author of the novel "Die Nanga-Notizen" and the Luis Trenker biography "Bera Luis," tells with a light touch about the relationship between these two completely different people. He casually depicts the passionate and always challenging coexistence at nearly 3000 meters above sea level. As an intimate connoisseur of the mountains, he not only pays homage to love with his book but also expresses a love letter to the magnificent nature and the extraordinary moods found in the solitude of the high mountains.
